Abstract: ABSTRACT OF THE DISCLOSURE:     Reversible,  articulated mechanical coupling and relevant seat, for linking anchorages under tension to the foundation bases.  The coupling is constituted by a hollow body open at its top, on whose outer surface a set of teeth protrude,  which are positioned in a sunburst fashion;  the body is closed at its bottom by a cylindrical appendix.       Inside the body of the coupling, a flexible element of ring shape is fastened,  inside which a ring in fastened in its turn, which is mounted on the upper surface, of cone-frustum shape,  or of spherical shape,  of the enlarged portion provided at the bottom end of a rod; said rod comes out from the top opening of the body of the coupling, and at its top end, it is welded to the bottom end of the anchorage.  The coupling seat comprises a cylindrical shell on whose inner surface grooves are provided, between which at least one set of entry grooves are provided in a number equal to the number of teeth of the coupling,  separated from each other by a set of grooves blind at their upper end, in order to engage the same teeth.   The coupling is stably engaged inside the relevant seat by completely introducing the coupling inside the same seat, and then lifting it.  During the insertion of the coupling, the teeth slide in the entry grooves of the cylindrical shell, and are guided by these in such a way that, when the coupling is lifted, the same teeth enter the blind-top grooves,  inside which they remain engaged.   The disengagement of the coupling from the seat takes place by completely sinking the coupling inside the seat and then extracting it from said seat.   When the coupling is sunk, the teeth are guided by the grooves of the cylindrical shell in such a way that, when the coupling is lifted again, the same teeth enter the entry grooves, making it possible the coupling to be extracted from the seat.

Abstract: ABSTRACT OF THE DISCLOSURE A particle storage chamber in a circulating fluid bed boiler having fluidizing means therein to tumble and fluidize the collected ash and ash coated particles. Due to the fuel burned, these ash and ash coated particles contain sodium and potassium compounds which react to lower the eutectic point of the particles thereby causing them to agglomerate or enter. By fluidizing these particles, they are prevented from reacting through surface contact.  Consequently, the ash and ash coated particles do not agglomerate or sinter thereby maintaining the individual characteristics of these particles and allowing smooth flowability for recirculation to the primary furnace zone.

Title: Method and apparatus for measuring the lead current in a pacemaker
Inventor: THOMPSON DAVID L
IPC: A61N1/362
Filed: 1989-09-18
Granted: 1993-04-27
Abstract: ABSTRACT          Disclosed is an improved pacemaker arrangement which permits the measurement of output current to the heart so that, if necessary, a physician can adjust the output of the pace-maker.  Prior art pacemakers include a series resistor in the output current path and the voltage drop across it can be measured and telemetered out.  This requires a high precision resistor to reduce measurement errors and,  if it fails, a "no output" condition can result.  Also, the resistor wastes output energy.  The present invention uses a large number, e.g. 200, of field effect transistors (FETS)  operated in parallel to discharge a capacitor through the heart tissue.  Pacer lead current is monitored by measuring current through a small number, e.g. 2, of the FETS.    The current monitoring function is performed by a current-to-voltage converter coupled to an A/D converter.   The voltage from the current-to-voltage con-verter may be applied through additional circuitry to the gates of the FETS to provide for a constant current output pulse.

Granted: 1993-12-14
Abstract: ABSTRACT            The invention relates to a switching network for a communication system, which is structured like a space-division multiplex switching network comprising m/l stages which include auxiliary lines and have each a trunk line and in which cells are transmitted in accordance with a time-division multiple access method and the cells are switched through on the basis of the routing information contained in the cell header and in which the cell arriving at the auxiliary line is written into the buffer dedicated to the trunk line if the routing information and address of this trunk line match and in which a decision circuit is included.  The switching network is specifically suitable for use with asynchronous time-division multiple access methods.  Each stage of each auxiliary line is assigned a memory to which are applied the results of the comparisons of the routing information and address of the trunk line.  The contents of the memory are applied to the decision circuits which, on the basis of these contents, determine the order in which the cells stored in the buffers are read out.

Abstract: ABSTRACT OF THE INVENTION      An optical communications systems, e.g. a telephone system, comprising means to accept even electrical communication signals from transmitting sta-tions, modulate an optical signal with said signal from the transmitting station (20) and, using time-division-multiplexing (TDM), provide a resultant optical com-munication signal to a central station (908) which utilizes a frequency-division multiplexing (FDM) system for handling incoming optical signals before passing the optical communication signals on the receiving sta-tion which utilizes time-division-demultiplexing means (400, 401, 402, 403) and, where necessary, reconverts the optical signal to an electrical communication signal. Particular advantages of the system are that it can handle and switch a very large number of signals and that it can be utilized in a hybrid communications system wherein, for example, users of the system can maintain conventional electrical entrance wiring (22) and conventional non-2optical telephones and yet inter-face readily with optical street lines (26, 28) of the system. Particular aspects of the invention are novel modulating and signal-selection devices.
